WILLIAM F. KELLEY, OF SEATTLE, WASHINGTON.

WAVE-MOTOR.

Specification of Letters Patent.

Application aled February 8, 1911. Serial No. 807,405.

To all whom it may concern:

Ila it known that I, Wnmmat F. KELLEY, a citizen of the United States of America, and a resident of the city of Seattle, in the (utility of King and State of Washington, have invented certain new and useful Improvements in Wave-Motors, of which the following is a specification.

My invention has for its primary object the provision of a novel construction wherein oscillatory motion of driving mechanism, driven through impact of the waves, is converted into a continuous rotai movement.

Further my invention resi es in the pror vision of means affording a yielding connection between the driving mechanism and the mechanism or load driven thereby.

Another object is to provide a prunary mover with a comparatively broad sectional impact receiving portion or face the component sections thereof being disposed abreast and being supported for independent movement.

Other objects will be set forth as my description progresses and those features of construction, arran ements and combinations of parts on which I desire rotection succinctly defined in my annexed c aims.

Referring to the accompanying drawings wherein like numerals of reference indicate like parts throughout the several views: Figure 1 is a perspective illustrating my invention in such form as now preferred by me. Fig. 2 is a fragmentary side elevation showing one unit of the system, parts being broken awa Fig. 3 is a fragmentary plan, and Fig. 4 1s a transverse section of the upper portion of the pier and adjacent mechanism taken on line 4-4 of Fig. 3.

In carrying out my invention I refer to employ a plurality of units 1, w ich are mounted on a suitable elevated sup )ort, as for example, a pier .2, and conuectet to cooperate in the development and transmission of power obtained from the force or impact of the water in motion. These units being identical in construction, a description of one will obviously sutlicc.

Reference numeral 3 indicates what I term the primary mover or driver or that part upon which the waves act directly for imparting motion thereto, the same consisting of a ilurality of paddles 3 arranged abreast for independent movement, whereby I am enabled to provide a comparatively broad active or impact receiving face which will in a great measure, obviate disastrous results due to torsional strain imposed by waves moving obliquely to the plane of the paddles.

The active faces of paddles 3' comprise panels which are mounted by guide eyes 4 for vertical ad'ustment in swing frames 4, and connected y cables 5, or the like, with respective drums 0, mounted on support 2, as shown, through which controlling mechanism the extent of projection of said panels into the water can be regulated, as will be readily understood. Swing frames 4: comprise side bars suitably connected to obtain rigidity, and having their upper end or tions projecting through slots '2 of the eck of support 2 and provided with outwardly projeztmg stud shafts 7, journaled in bearin s eference numeral 9 indicates a shaft extending crosswise of support 2 over paddles 3' and journaled in stands 10. On shaft 9 I mount two airs of loose wheels 11. conveniently in t e form of ooved pulleys, each air of which is associated with a respectlve addle 3', for a par ose hereinafter ma e apparent. The pul eys 11 have releasable driving connection with shaft 9, to turn the latter continuously in one direction through the medium of pawl and ratchet devices 12, the ratchet wheels of which are fixed to said shaft while the engaging pawls are carried by the pulleys, as

shown.

Connected with each addle 3'. as by chain connections 15, are t exible connections 13, 13', as for example cables or the like, whose end portions lead from opposite sides of said paddle over guide sheaves 14: and thence up to pulleys 11 on which they are engaged, each being given one or more turns on a respective pulley with the winding of one extending relatively reversely to that of the other to thereby enable each flexible connection to rotate the pulley ll engaged thereby. through an active step during movement of paddle 3' in a respective direction.

Reference muncral 16 indicates a pulley loosely mounted on shaft J and havin;' a yielding connection therewith. as by a spiral siring 17, through the medium of which he load is picked up easily and abrupt shocks to the addles and to the mechanism driven from s mft 9, obviated.

The pulleys 16 of the several units are connected by endless connections or belts l8 Patented May 30, 19M.

to operate as a single plant for sup dying power for mechanical operations, as or, exam )lc the driving of a dynamo 20.

late I have herein shown and described a construction which will carry out the functions assigned to it, I wish it understood that I reserve the ri ht to make various changes in the minor etails of construction without de iarting from the s iirit of my invention. "or cxannle, paddles 3' can be otherwise arranged tlian abreast, and wheels 11 can be employed singly instead of in pairs. The latter arrangement is, however, preferable inasmuch as it permits of a drivmg impulse being given to shaft 9 during each stroke of the related paddle 3'.

Having thus described my invention what I claim as new,and desire to secure by Letters Patent of the United States of America, is:

1. A wave motor comprising a support, a shaftjournalcd on said su port a pair of power transmission wheels oosely mounted on said shaft, releasable driving connections connecting each wheel for movement with said shaft in one direction, a paddle mounted on said support for movement in relatively opposite directions aides on opposite sides 0 said paddle, and ilexible connections each having their end portions secured to and leading from respective sides of said paddle and over said guides to said wheels, the intermediate portions of said flexible connections each engaged with a respective wheel for effecting an alternative operation of said wheels in one direction during movement of said paddle in reverse directions.

2. A wave motor comprisin a support, a drive shaft journaled on sai sa port, oscillatory means mounted on sai support for movement by wave impact, said means comprising a plurality of independently movable. paddles arranged abreast, loose wheels on said shaft arranged in pairs each of which )llilS is associated with a respective paddle, releasable driving connections connecting said wheels with said shaft for movement therewith in one direction, and a pair of flexible connections between each pair of wheels and a paddle conneetiu the respective wheels of a pair for alternative movement in one direction during movement of the related paddle in reverse directions. 3. A wave motor comprising a support, a shaft journaled on said support, a pair of power transmission wheels loosely mounted on said shaft, releasable driving connection connecting each wheel for movement with said shaft in one direction, a paddle mounted on said support below said shaft for movement in re ativcly opposite direction, aides on opposite sides of said paddle, and t exible connections each engagial with a respective wheel and with said guides and secured to said paddle for etl'ecting an alternative operation of said wheels in one direction during movement of said paddle in reverse directions. I

4. A wave motor comprising a sup wit, a drive shaft mounted for rotation, osci latory means mounted on said support for movement by wave impact, said means comprising a plurality of indepemlently movable paddles arranged abreast, power transmission wheels having releasable driving connection with said shaft for movement therewith in one direction, said wheels bein arranged in pairs each of which is associated wit 1 a respective paddle, and operative connections between each pair of wheels and a paddle connecting the respective wheels of a pair for alternative movement in one direction durin movement of the related paddle in reverse irections.

5. A wave motor comprising a support, oscillatory means mounted on said support for movement by wave impact, said means comprising a plurality of independently movable paddles arranged abreast, a drive means mounted for rotation, loose wheels on said drive means arranged in pairs each of which pairs is associated with a respective paddle, releasable driving connections connecting said wheels with said drive means for movement therewith in one direction, and o erative connections consisting of a pair 0 flexible members between each pair of wheels and a paddle connecting the respective wheels of a pair for alternative movement in one direction during movement of the related paddle in reverse directions.

6. A wave motor comprising a support, oscillatory means mounted on said support for movement by wave impact, said means comprising a plurality of indepemlcntly movable paddles, a drive means mounted for rotation. loose wheels on said drive means arranged in airs each of which pairs is associated witi a respective paddle, releasable means connecting said wheels with said drive means for movement therewith in one direction, and a pair of flexible connections between each pair of wheels and a paddle. connecting the respective wheels of a pair for alternative movement in one direction during movement of the related paddle in reverse directions.
